Bacteria and Viruses are commonly found in nature ,but not all are harmful. Transmitted Via
Food Borne
Person-Person
Air Borne
Vaccine- A preparation of weakened or killed pathogens. When injected a vaccine makes the body produce an immunity to the disease. Antibiotic- Compounds that block the growth and reproduction of bacteria. They can be used to cure many bacterial diseases.
Bacterial Diseases
Can be cured by Antibiotics and prevented by vaccines
Can Reproduce on their own
Ex: Common Cold, E. Coli
Bacteria can produce disease in two ways. Some damage cells and tissues by breaking down the cells for food. The second way bacteria infect the body is that they release toxins that interfere with normal host activities. Bacterial Diseases can be transmitted Via Food Borne, Person to Person, and Air Borne.
Viral Diseases
Can be prevented by vaccination
Cannot reproduce on its own
Ex: HIV, Influenza, Hepatitis, Polio
Like Bacteria, Viruses produce disease by disrupting the body's normal equilibrium. Viruses attack specific cells in the body.
